"Vera has been a close family friend for a long time and we had talked about this moment for years," Kardashian, 30, wrote on her blog. "So when it came to picking my wedding dress designer, she was the first person I thought of. No one designs gowns the way she does!"

The reality star and her sister, Kourtney, were seen at Wang's NYC store last month, fueling speculation that Kim would be wearing a dress by the famed designer when she said "I do" to Kris Humphries.

Her sister, Khloe, told E! News she wanted Wang, 62, to design her sister's gown: "Just because I love her, and I feel like when you think of wedding, you think of Vera Wang. I think it would be a perfect fit."
